I need help. I know very little about computers so bear with me lol. I downloaded this game (my first on a PC) version 1.4 and have played all the content. When I downloaded version 1.5 I thought it would just add the update and let me play, but it creates a 2nd application (update file 1.5) that when started instantly crashes. But my old application 1.4 still works fine. What am I doing wrong?
